IMPROVEMENT IN MACHINES I-"OR CUTTING PAPER COLLARS.

Specification forming part of Letters Patent No. 171.524, dated December 28, 1875; applicationfiled November 22, 1875.

To all whom it may concern.-

Be it known that I, HORACE J. MEDBERY, of Ballston Spa, county of Saratoga and State of New York, have invented a new and useful Improvement in Machinery for Cutting Gollars, Cuffs, Bosoms, Envelopes, Tags, and articles of a similar nature, which improvement is fully set forth in the following specification, reference being had to the accompanying drawin gs.

The object of my invention is to rapidly cut collars and other articles from long strips or rolls of cloth-faced paper or other suitable material, by passing the material between two rollers, one of which-preferably the upperis provided with knives for the straight edge of the article, and bent knives to-cut the curved edge, so that at one operation, as the rollers revolve, the material may be instantly cutinto the shape desired.

It is well known to manufacturers that, of the articles mentioned, various sizes are required for the marketas, for example, of collars, no less than from ten to thirteen sizes being in use in each style; and in other machines of this nature a full set of knives is required for each size; but in my invention I adapt one set of knives for cutting the ends of the collars, &c., to all the sizes, thus saving the cost of knives and the trouble of sharpening so many sets.

Figure 1 of the drawings is a front elevation of a machine embodying my invention. Fig. 2 is a top view. Fig. 3 is a vertical transverse section on the line of m m, Fig. 1. Fig. 4 is a detached view of the knife-bearing roller upon its shaft. Fig. 5 is a detached plan view of the end-cutting knives and the block to which they are permanently affixed. Fig. 6 is a plan of the material when cut.

In the drawings, A is the knife-bearing roller on its shaft a, mounted on its bearings b b in the frame of the machine. Upon roller A are two shells or sleeves, c c, which are easily slipped on or off, and which, when in revolution, are rigidly fixed to the roller by means of set-screws, or keys in grooves, or other ordinary and convenient appliances, and which, as can be seen in Figs. 1, 2, and 4, constitute an almost solid roller. Upon each of said Sleeves are sharp-edged knives,dd,- such as are commonly used for similar purposes, and which, as the roller revolves, cut the straight edge of the collar, and upon eachof said sleeves is also the diagonally-arranged knife 0 e, the ends thereof joining with the end-cutting knife ff, thus forming a continuous cutting-line. All the knives are sharp-edged, and are easily kept so, which cannot be the case with engraved dies, or punches and dies out upon rollers. Said knives are fixed upon the sleeves by means of screws. Between the knives, where the waste is likely to collect and clog, is a filling of rubber or other elastic material, for the purpose of pressing out and throwing off the collars and end'cuttin gs as soon as released fromthe pressure of the rollers through which they pass. Beside the blades of each of the knives there is necessarily a :space-of about one-sixteenth of an inch or less, so that the stock may be cut cleani. 6., without ragged edges-the space being filled in flush with rubber or other elastic packing. B is the opposing roller, mounted upon a shaft, 9 g, having its bearings at hit. This roller is covered with green hide, rubber, paper, cotton, or other material which is not likely to'blunt the edges of the knives pressing upon it. The pressure of this roller upon roller A is regulated by means of adjusting-screws, as seen in Fig. 3, each journal resting upon a sliding bed plate or block, beneath which is a spring, is, which rests upon a sliding block, on which the screw directly acts, as must readily be understood upon looking at said Fig. 3. O is a feeding-table in front of the rollers, the width of the guides apart being gaged by means of set-screws m m passing through the plates an, which slide in a groove in the table, as seen in Figs.2 and 3.- D is an ordinary belt-pulley for transmitting motion to the shaft a.

The other parts of the machine do not require explanation, further than what is furnished by the drawings.

The mode of operation of my invention must be obvious. The shaft to being set in revolution by a band upon the rigidly-fixed pulley, the roller A communicates motion to roller B, with which'it is in contact. The strip of stock, then passed between A and B, is cut by the knives on A, the articles and waste passing out at the other side. if desired to change outting from one size of article to :another size, thesleeveszmay readily be slipped 0E fromthe roller, and another pair of sleeves be slipped on and made fast, and as the ends of all sizes of the collars are alike in size and shape, the solid knives ffare adjusted to any of the other sets of knives.

It is obvious that in my improved machine the cost must be much less than if thelknives f f were but a portion of one continuous knife, while, by reason of my arrangement of knives e e, the waste of stock is reduced to a minimum. What I claim as my invention, and desire to secure by Letters Patent, is-

1. The mode of cutting collars, cufi's, envelopes, tags, and articles of a similar nature,

from stock, by means of sharp-edged knives arranged upon sectional sleeves on roller A,

acting upon roller B, revolving under pressure,

substantially as described.

2. The combination of roller B, sectional sleeves, c c, knives d d, e e, and f f, alllconstructed as and for the purpose described.

3. Ina machine for cutting collars, cufl's, and articles of a similar nature, the combination of the sleeves c c with the knives f f, substantially asdescribed.

4. In a machine for cutting collars, cuffs, and

articles of a similar nature, the combination of roller A, sleeves c 0, knives d d, e e, and f f, the covered roller B, all constructed and operating as described. l
